ProteMac has updated ProteMac Meter (http://www.protemac.com/Meter/), the network activity monitor and network traffic logger utility for Mac OS X (10.4 and higher), to version 3.7. The upgrade sports speed increases.
ProteMac Meter allows control network activity for each application on your Mac, showing you what was transmitted and to where. It shows information about each connection: application network connections, host availability, remote host name, amounts of incoming and outgoing traffic through connection or application, timestamps of the first and last activity, application that initiated or accepted this connection, full path to the application the process belongs to, and much more. The traffic summary indicator shows an upload and download speed graph and traffic totals specially for selected application.
You can use ProteMac Meter right from your menubar floating diagrams to see the application and network bytes flow. It costs US$29.95 for a single-user license.
